Problems solved by technology

[0007] Nonylphenol is more harmful to aquatic ecosystems, but at present, there is no water quality standard for nonylphenol in China, and there is no wastewater treatment technology specifically for nonylphenol. Therefore, it is urgent to provide a nonylphenol water quality standard The formulation method and the removal method of nonylphenol in water

Embodiment 1

[0044] A method for formulating nonylphenol regional water quality standards, comprising the following steps:

[0045] S1. Collection and screening of toxicity data: collect toxicity data of species in the area, and exclude toxicity data of non-native species;

[0046] Based on the characteristics of the aquatic biota in the Taihu Lake Basin, the published literature reports at home and abroad were reviewed, and according to the minimum species requirement principle and the toxicity data screening principle in the "Technical Guidelines for the Establishment of Water Quality Standards for Freshwater Aquatic Organisms" (HJ 2017-831) in China, Collect the aquatic ecotoxicological data of biota species in the Taihu Lake Basin, and try to select species in Taihu Lake. Species that are widely distributed in Jiangsu, Zhejiang and the Yangtze River can also be regarded as Taihu Lake species.

[0047] Specifically, it includes acute toxicity data, chronic toxicity data (reproductive to...

Embodiment 2-5

[0091] A method for removing nonylphenol in water, which is to use a composite reagent to absorb nonylphenol-containing water, and the composite reagent is composed of the following raw materials in parts by weight: 100-300 parts by weight of corncob biochar and gas phase dioxide 10-50 parts of silicon, and 50-100 mg of the above compound reagent per liter of nonylphenol-containing water.

[0092] The composition and addition amount of the composite reagents of Examples 2-5 are shown in Table 6.

Abstract

The invention discloses a nonyl phenol regional water quality standard making method. The method comprises the following steps: S1, collecting and screening toxicity data; S2, deriving a water qualitystandard for protecting aquatic organisms; S3, making a water quality standard; S4, evaluating the water quality standard: S41, evaluating the water quality standard, including the water quality standard and the standard current situation of nonylphenol aquatic organisms at home and abroad; S42, analyzing the regional concentration environment; S43, economically analyzing; S44, analyzing a methodand a detection limit; S45, performing expert review. The standard value for protecting the water quality of the aquatic organisms is reasonable and feasible, can provide proper protection for the aquatic organisms, and is also suitable for the current environmental management level of China; the invention further discloses a nonyl phenol removal method in the water body, nonyl phenol in the water body can be effectively removed, the effluent concentration is lower than 2.8 mu g / L, and the NP daily management standard limit value requirement is met on the wastewater treatment technology.

Description

technical field [0001] The invention belongs to the technical field of water environment protection methods, and in particular relates to a method for formulating nonylphenol water quality standards and a method for removing nonylphenol in water bodies. Background technique [0002] Nonylphenol (Nonyl Phenol, referred to as NP), also known as nonylphenol, the molecular formula is C 15 h 24 O, the molecular weight is 220.24. Nonylphenol is an important fine chemical raw material and intermediate. Its appearance is a colorless or light yellow liquid at room temperature, with a slight phenol smell. The relative density is 0.94-0.95. In petroleum ether, insoluble in water. Nonylphenol is mainly used in the production of surfactants, antioxidants, textile printing and dyeing auxiliaries, lubricating oil additives, pesticide emulsifiers, resin modifiers, resin and rubber stabilizers and other fields. [0003] Nonylphenol is a kind of Aps (alkylphenols, alkylphenol) produced by...
